Via JavaScript

Gonesa tabable tabs kuburikidza neJavaScript (tebhu yega yega inoda kuvhurwa yega):

const triggerTabList = document.querySelectorAll('#myTab button')
triggerTabList.forEach(triggerEl => {
  const tabTrigger = new bootstrap.Tab(triggerEl)

  triggerEl.addEventListener('click', event => {
    event.preventDefault()

Nzira

Asynchronous nzira uye shanduko

Yese nzira dzeAPI dzine asynchronous uye dzinotanga shanduko . Vanodzokera kumunhu anenge afona pachangotanga shanduko asi isati yapera . Pamusoro pezvo, kufona kwenzira pachikamu chekuchinja kuchafuratirwa .

Ona zvinyorwa zvedu zveJavaScript kuti uwane rumwe ruzivo .

Inomutsa zvirimo sechinhu chetabhu.

Iwe unogona kugadzira tabhu muenzaniso nemugadziri, semuenzaniso:

const bsTab = new bootstrap.Tab('#myTab')

Nzira	Tsanangudzo
`dispose`	Inoparadza tebhu yechinhu.
`getInstance`	Static nzira iyo inokutendera iwe kuti uwane iyo tab muenzaniso yakabatana neiyo DOM chinhu, unogona kuishandisa seizvi: `bootstrap.Tab.getInstance(element)`.
`getOrCreateInstance`	Static nzira inodzosa tabhu yakabatana neDOM element kana kugadzira imwe nyowani kana isina kutangwa. Unogona kuishandisa sezvizvi `bootstrap.Tab.getOrCreateInstance(element)`:.
`show`	Inosarudza iyo tabhu yakapihwa uye inoratidza yakabatana pane yayo. Chero imwe tab yakambosarudzwa inova isina kusarudzwa uye pane yakabatana nayo inovanzwa. Inodzokera kumunhu arikufona tebhu isati yanyatsoratidzwa (kureva kuti `shown.bs.tab`chiitiko chisati chaitika).
